SIGNAL.

Application led April 25, 1923. Serial No. 634,588.

To al whom t may concern:

Be it known that I, OLIVER B. HALSTEAD, a citizen of the United States of America. and resident of Ontario, in the county of San Bernardino and State of California, have invented certain new and useful Improvements in Signals, of which the following is a specification.

This invention relates to signaling devices for indicating the intended direction of travel of the user of the device when it is installed in an automobile or the like, the said invention having for an object the provision of no'vel means whereby a signal with legends thereon may be exhibited at the side of an automobile 1n order that it may be visible from the rear or'from the front;

and the said invention furthermore has for an object the provision of novel means for oscillatably mounting and actuating an arm carrying the signal, while atA the same timeof construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and-claimed.

In describing the-invention in detail, ref'- erence will be had to the accompanying drawings forming part }of this application wherein like characters denote corresponding parts in the 4several views, and in whichl Figure 1 illustrates a view in elevation of a deviceembodying the invention installed on a fragment of a windshield;

Figure 2 illustrates a longitudinal sectional view of the signaling mechanism and Fi ire 3 illustrates a sectionalview on the l1ne 3 3 Vof Fig. 2 omitting the driven gear wheel. p

In these drawings, 5 denotes a suitable frame that may be attached in anyappropriatel way to windshield frames or automobile body frames, and the inventor does not wish to be limited with respect to the manner of installing the device. The face plate 6 is segmental and has a plurality of recesses 7 in its face which serve as seats 'for the yieldable pin 8 that is 'carried -by the crank 9, in order that the crank and partswhich it operates may be held in the' different po sitions .of adjustment indicated by the legends on the face late, the le nds bein here displayed as ight, Le Slow ,y Backnr Stopv The crank 9 is secured on a hollow shaft 10 and the shaft 10 is journaled in the frame and the said sha-ft also rotates in a gear wheel 11 that is stationary on the frame or face plate. Of course the toothed mem- .ber 11, termed a wheel, may be in the nature nected to it that serves as a conduit for the conductors 13A for supplying current to a. lamp 14 which is on the outer end of the arm. The lamp is supplied withccurrent from a source of electricity through suitable wiring diagraminatically shown at A, andA as this wiring may be changed ,to stuit particular requirements, -it need not, it is thought, be described in detail. A sleeve 15 is rotatable onor withrelation to the arm, andthe said sleeve has a gearrw'heel 16 secured to it vthat meshes with the gear wheel 11, so that when the shaft 1 0 is rotated, the arm 12 will be oscillated carrying the sleeve which will vbe rotated through therengagement of the gear wheels 11 and 16. A casing 17 on the outer end of the sleeve receive-s the arm and lamp, and this casing is preferably provided with a series of lenses or glass-panelslS having appropriate legends thereon corresponding preferably -to the legends on the face plate, and the parts are so arranged that when the crank 9 has been moved to positions yin-v dicated'by the legends, a legend' corresponding to that at which -the crank comes to rest is displayed at thencasing so that it can be read either from the front, or rear of the automobile on which the device is installed. Preferably, however, the parts would be so arranged that the legend would be displayed at the rear in order that an approaching traveler may know the intended direction of travel of the user of the device.

Suitable bearings or bushings may be provided for the shaft 10. but as these' are details of construction whichfthose skilled in the art Will understand, it is believed unnecessary to describe them more fully.

It will be apparent from an inspection of the drawing that the oscillation of' the arm *Will cause' the Wheel 16 to travel in engagementY with. the Wheel 1i; and that the engagement of these wheels will canse the rotation of the sleeve to a greater or less extent, according to the degree of oscillavtion of the arm Y 'iaeepese In a signal, a bracket having a shaft journaled therein, a toothed element on Vthe bracket concentric with the shaft, anarm extending from the shaft and having a lighting fixture on its outer end, a sleeve rotatable on the anni, a toothed Wheel securedto the sleeve" and meshing Ywith the toothed element \on the bracket, a handfe for rotating the shaft, and a lamp casing Yon the outer end of the sleeve enclosinga the lighting lixturecarried by .it-he arm ofv the shaft.
